Yesterday’s Beautiful Music featured a young vocal ensemble — Stellenbosch University Chamber Choir — based in Stellenbosch, South Africa. The group was new to me, and their versatile talent is outstanding and deeply compelling. So today’s Beautiful Music is another of their performances — this time it’s a medley of African songs. Assistant conductor Jade Paige is one of the soloists, along with Clarina Solomon and Phindile Mgobozi, from this 2017 concert recording.
